Track changes in a Shared Workbook

1. Be certain that you want to use this method before continuing. Shared Workbooks have limitations, and one in particular is the inability to edit using Excel for the web. Therefore we highly recommend co-authoring, which is the replacement for Shared Workbooks.

2. Click Review > Share Workbook.

   Note that in newer versions of Excel, the Share Workbook button has been hidden. Here's how to unhide it.

3. In the Share Workbook dialog box, on the Editing tab, select the Allow changes by more than one user at the same time check box.

4. Click the Advanced tab.

5. Under Track changes, click Keep change history for and, in the days box, type the number of days of change history that you want to keep. By default, Excel keeps the change history for 30 days and permanently erases any change history that is older than this number of days. To keep change history for a longer than 30 days, enter a number that is larger than 30.

6. Click OK and, if you are prompted to save the workbook, click OK to save the workbook.

1. Click Review > Track Changes, and then click Accept or Reject Changes.

   Note that in newer versions of Excel, the Track Changes button has been hidden. Here's how to unhide it.

   • To accept or reject changes that are made after a particular date, select the When check box, click Since date in the When list, and then type the earliest date for which you want to review the changes.

   • To accept or reject changes that are made by another user, select the Who check box and then, in the Who list, click the user whose changes you want to review.

   • To accept or reject changes that are made by all users, clear the Who check box.

   • To accept or reject changes that are made to a specific area, select the Where check box, and then type the cell reference of the worksheet range.

   • To accept or reject changes to the entire workbook, clear the Where check box.

4. Click OK, and then review the information about each change in the Accept or Reject Changes dialog box.

   • Hold down CONTROL and click the History tab at the bottom of the history sheet, and then click Move or Copy.

   • In the To book area, click the name of the workbook you want to move the sheet to, or click (new book).

   • Select the Create a copy check box, and then click OK.

   • Save the workbook that contains the copied history sheet.

You can use change tracking to log details about workbook changes every time that you save a workbook. This change history can help you identify any changes that were made to the data in the workbook, and you can then accept or reject those changes.

Change tracking is especially useful when several users edit a workbook. It is also useful when you submit a workbook to reviewers for comments and then want to merge the input that you receive into one copy of that workbook, incorporating the changes and comments that you want to keep.

When changes are made in the shared workbook, you can view the change history directly on the sheet or on a separate history sheet. Either way, you can instantly review the details of each change. For example, you can see who made the change, what type of change was made, when it was made, what cells were affected, and what data was added or deleted.

When you use change tracking, consider the following:

• Change tracking differs from the undo operation and does not create a backup copy    

  You might expect that change tracking creates a backup copy of the workbook before changes are made, or that you can undo any of those changes. Unfortunately, you cannot use the change history to revert changes by undoing them or by restoring an earlier version of the workbook. However, the history sheet includes a record of all deleted data so that you can copy that data back to the original cells in the shared workbook.

  Because change tracking is not designed to help you return to earlier versions of a workbook, you should continue to back up workbooks that have change tracking in effect.

• Some types of changes are not tracked    

  Changes that you make to cell contents are tracked, but other changes, such as formatting changes, are not tracked. Some Excel features are unavailable in shared workbooks and therefore cannot be tracked.

• The change history is kept only for a specific interval    

  By default, when you turn on change tracking, the change history is kept for 30 days to keep the size of the workbook manageable. However, you can increase or decrease the number of days of the change history that you want to keep. To keep the change history indefinitely, you can specify a large number of days. You can also make periodic copies of the history information.

• The oldest part of the change history is periodically deleted    

  Excel determines the change history that is kept by counting back from the current date. Each time that you close the workbook, Excel deletes any part of the change history that is older than the number of days that were in effect the last time the workbook was saved.

  For example, if you are keeping 30 days of change history, and you open a workbook for the first time in two months, you will be able to view the history from two months ago. However, when you close this workbook, the history from the previous 30 days (31 to 60 days ago) is deleted.

Excel provides the following ways to access and use the stored change history.

• Onscreen highlighting    

  Excel can outline changed areas in a different color for each user and display the basic details as a comment when you rest the pointer over each changed cell. Onscreen highlighting is useful when a workbook does not have many changes or when you want to see at a glance what has changed.

• History tracking     

  Excel can display a separate history sheet that provides a printable list of change details on which you can filter to find the changes that you are interested in. The history sheet is useful when a workbook has many changes or when you want to investigate what occurred in a series of changes.

• Change reviewing    

  Excel can step you through the changes in sequence so that you can decide whether to accept or reject each change. This method is useful when you are evaluating comments from other users.
